oil prerssure spring change
has any one tried any of the oil pressure spring changes to increase oil pressure. I see baisley has 2 offered a 15% and 30% increase spring pressure. at idle assuming my pressure sender and gauage are failry accurate I am about 12 psi at idle and about 2800 rpm im about 30 . when cold it runs about 34 even at lower rpms. I have an andrews 32 cam in right now and notice rocker noise until the oil pressure hits about 28 psi on my guage.
after looking at a picture i took, the service manual isnt very clear either, I am wondering if the roll pin can be pushed out towards the cam box to allow the spring to come out with out hitting anything as its being pushed out. I cant remember if anything is directly behind it when I had the cams out.
what im wondering has anyone tried these springs, what does oil pressure run at now and how did it effect your rocker noise.

I respect your right to have an opinion.
can you estimate how long before my motor grenades so I can properly budget a replacement.
with all the posts of inferior Chinese parts on these bikes you believe the stock spring is doing its job

THe Axtell bypass sounds like a good plan, I should have had that done when my TW222 cams went in. Could not afford a Feuling oil pump which is hi flow.

That Axtell spring must be popular. I could have sworn it was like $50 when I looked at it back in Jan/Feb this year.

Last fall I installed the Axtell bypass kit in my 2009 SG. The intent was to quiet down the Woods lifters which are a little quieter, but no significant change. The top end noise was never an issue. The oil pressure is 7psi at hot idle, 23psi off idle to under 2000 RPM and 40psi at cruise RPM. The Axtell kit bumped idle oil pressure up a 2-3 psi, mid range about the same and cruise went from 32 to 40 psi. Overall, less lifter noise at mid range RPM with higher idle and cruise oil psi. The engine temp feels to run a bit cooler with the Axtell kit and K&P oil filter.
